“…[28], where two of the samples studied in the present work (Texture1 and Texture2) originate. In contrast to this previous study [28], one of the main focusses of the present work is the detailed TEM investigation of these samples with two different starting textures in order to characterize dynamic precipitation during ECAP at 150 C. This allowed exploring the effect of the initial texture on the dynamic precipitation characteristics upon severe plastic deformation. In addition to Texture1 and Texture2 specimens, another Texture2 specimen (Texture2-4) was sequentially processed for four passes at 150 C to investigate the effect of the level of plastic deformation on DRX and dynamic precipitation.…”

“…The density of ɸ 0 particles (indicated by arrows) is relatively lower and their size (~50 nm) is smaller compared to those observed in twin/grainboundary DRX regions of the Texture1 specimen. Please note that the size of DRX grains is also smaller in the Texture2 specimen compared to the ones in the Texture1 specimen [28].…”

“…Detailed microstructural characterization and simulation results of the Texture2 specimen showed that there are limited twinning activities during ECAP at 150 C [28]. In addition, after ECAP the grains become smaller, divided, and elongated with dense, low angle grain boundaries in comparison to the Texture1 specimen [28].…”

High-frequency impacting and rolling was applied on AZ31B magnesium alloy to obtain a gradient nano-structured surface. Surface characteristics were experimentally investigated, and the nanocrystallization mechanism is discussed in detail. Results showed that the gradient nano-structure with the characteristics of work hardening, compressive residual stress and a smooth surface was induced on the treated surface. Grains on the top surface were generally refined to around 20 nm. Twins, dislocations and dynamic recrystallization dominated the grain refinement process. Fatigue strength of the treated specimens corresponding to 10 7 cycles was increased by 28.6% compared to that of the as-received specimens. The work hardened layer induced by high-frequency impacting and rolling is the major reason to improve fatigue life.

In this study, the effects of torsion strain and strain rate on microstructure and hardening behavior of extruded AZ31 Mg alloy rods are investigated. Torsion deformation can generate abundant extension twins and dislocations and cause the rotation of c‐axis toward extrusion direction. These microstructures exhibit gradient distributions along the radial direction of torsion‐deformed rods. Torsion deformation can effectively enhance the hardness of AZ31 rods. The gradient microstructure leads to a gradient hardness distribution in torsion‐deformed rods. High strain rates can enhance the hardening effect via torsion deformation by promoting increment of dislocation density.
